nice work on the slides. A few comments.<br>

Done.<br>

- p5: following our discussion, I thought about the stand more.
We can mount the pivot attachment to the centre holes, so that the
Mini Cal has the SiPMs outside the beam and to the side. The
pivot will be used to orient it so that the electrons are coming
in on a plane perpendicular to a plane bisecting the module along
its principal axis. We can then rotate the entire device with its
stand, to achieve angles from 90-20, ie go from 15X0 to 44X0. In
other words, we would not need to make a transition piece.<br>
</blockquote>
We thought about this option. In this case the rotation axis
becomes perpendicular to the floor, but should be at 60deg. The
transition piece puts the rotation at the correct angle. Tim and
Chuck will be looking at this carefully this morning to see how we
can do this.<br>

-p6: at 5 pass, we have 5.542 GeV, and at the 30% E/E0 point that
is almost 1.67 GeV. You have 1.2 GeV. <br>

Changed to ~1.5 GeV. We will likely sit a fixed E/E0, but it may not
reach 30%. We will have to survey the geometry carefully to
determine where the prototype can fit.<br>

The rest looks peachy.<br>
<br>
Cheers and have fun in the presentation, Zisis...<br>

Comments are more than welcome. Considering time
constraints, I will try <br>
to incorporate your suggestions.<br>
